Application filed February 12,1906. Serial No. 300,589.

To all whom, it' may concern:

Be it known that I, HANNIBAL I. KIMBALL, a citizen of the United States, residing in the borough of' lNIanhattan, in the county of New York, city and State of New York, have invented certain new anduseiul Improvements in Rolling-Presses, of which the following is a specification.

This invention relates to roller presses that form characters in printing plates by the rolling movement of a die, or a series of dies over the plate.

One of the objects of the invention is to produce an improved means for causing the die holding member to have a true rolling movement over the engraving plate, and to bp pressed into proper engagement with the ate.

p Another object of the invention is to provide in such a device a die holder that will carry a series of dies constituting a font oi type, which type is shii'table to bring any one of them to a printing position, and thereupon such selected type or die is advanced to a position to engage the printing plate upon the die holder being operated.

Another object of the invention is to provide improved means for shitting the engraving plate relative to the operating position of the selected die in the holder; and to further provide this latter means with mechanism whereby the said plate can be advanced either a certain unit distance or a multiple thereof, to accommodate the diiierent widths of the characters of the several dies.

A roller press embodying my invention is set forth in the accompanying drawings whereon Figure l shows the device in front elevation, certain portions being broken away to disclose other portions. Fig. 2 is an end view of the plate carriage shifting means.

Fig. 3 is a vertical section on the line 3-3 of Fig. l. Fig. 4 is a fragmentary perspective view showing the engagement of one end of the working member with the table. Fig. 5 is a view of a portion of the guide plate for the dies in the holder. Fig. 6 is a fragmentary .view showing the pressing member and its engaging portion of the working member. Fig. 7 shows a modification of the parts shown in Fig. 6. Fig. 8 is a perspective view of one of the dies. Fig. 9 shows three dies in side elevation. Fig. 10 is a fragmentary perspective view showing the selecting of a die and its movement to the printing position. Fig. 11 is a similar view in side elevation; and Fig. l2 is an enlarged view of the parts shown in Fig. 2.

The device as shown comprises essentially a table member T; a 'working member W having a rolling movement over the table; and a pressing member R operable between an arm of the table and the working member to Jr'orce the die in the working member into engagement 'with a plate on the table when the working member is rocked. The table T is shown as one integral member or casting having plate like end members l5 and 16 connecting the table portion 17; and also rovided with a longitudinal web 18 for strengthenmg purposes.

A carriage member 19 slides longitudinally on the table and has projections 20 and 21 sliding in grooves 22 and 23 that are formed between the table and -gibs 24 and 25. A lug 26 projects downward from the table and has a threaded aperture engaging a screw rod 27 rotatable in bearings in the end portions of the table but prevented from end wise movement. The rotation of this screw will reciprocate the table as desired. One end of the screw rod 27 projects beyond the lug member 16 and has secured thereto an operating arm 28, that may carry a handle portion 29. By turning this handle the carriage can be advanced. in either direction.

A plate P to be engraved may be secured resting on the table by means of two clamp members O O.

Two rods 30 and 31 are slidable transversely in the carriage plate as shown in Fig. 3 and can be clamped in adjusted positions by means of one or more screws 32 tapped in the lower part of the carriage to engage the rod. The clamps O are secured to the iront ends of the rods as shown in Fig. 3. The clamps each comprise a block 34 secured to the rod,

and a piece 35 having an aperture through IOO movement in engagement with the plate P is shown as comprising a body portion 37 connected with a handle portion 38 by web portions 39, such members being integrally connected. At each end of the body portion 37 is a disk 40 that has a rolling movement over a bearing member 4l of the table having a plane surface, so that the working member will have a cycloidal movement. The bear-l ing portions 41 may be separate blocks suitably secured to the table and have hardened bearing surfaces to prevent wear. Suitable means are provided to prevent slip between. the disk 4() and bearing surface 41, which may comprise a rack 42 secured to the block 41 and engaging with a gear segment 43 secured to the disk 40. Means are also shown to prevent end-wise movement during such rolling of the working member comprising an annular llange 44 on the disk 40 engaging a corresponding groove 45 in the block 41. This 'arrangement is identical at cach end of the working member and table as shown in Fig. 1. 1

rlhe body portion 37 of the .vorking member is provided with a channel 46, shown in Fig. 4, that has a groove 47 therein. The channel is of a size to lit the dies D shown in Fig. 8, a lug d on cach die engaging in the groove 47 thereby preventing the dies frein moving out of the groove, permitting only a shifting movement sidewise of the dies. A strip 48 is secured to the body member 37 of the working member and has a rabbeted portion 49 to permit the travel of the dies. At the middle portion of the working member, the strip 48 is provided with a slot 50, into which a die can be moved downward to engage the plate P and impress the same when the working member is rocked. If desired a resilient pressing means may be provided for properly positioning the die in such slot by having one side of the slot 50 Jformed of a block 51 movable to and from the stationary wall ol" the slot. Another slot 52 is made in the piece 48, leaving a piece 53 that contains an aperture in which slides a pin 54. This pin also slides in a bore in the portion 55 of the piece 48; the other end of the pin being secured to the movable block 51. In the secondslot 52 acoil spring 56 is connected with the pin to advance the same to move the block 51 into engagement with a die and press the latter against the opposite stationary wall of the slot. The spring 56 may engage a collar 57 fast on the rod 54, its other end abutting the portion 55 of the strip, to thereby advance the block 51.

An entire font of dies l) may be placed in the die holder constituting the alphabet, numerals and punctuation or other desired characters. The lower portion of each die is visible at the front and each may have inscribed thereon its character, as indicated in Fig. 10. The dies may be advanced to bring the desired one to register with `the slot 50, by any suitable means, such as by inserting a rod. into either end of the slot in which they operate, and pushing them along until the desired one is positioned. Each oi* the dies has a recess Q0, in its front edge that when the die is advanced to the registering position with the slot, will engage an arm 58 th at is normally held in such position by a spring 59. By this means the die is prevented from falling into the slot l50 upon being brought to registering position.

Suitable means are provided Jfor forcing the positioned die downward into operating position in such slot for engaging the plate l. The cam 6() is secured on a spindle 6]. having bearings in the portions 39 of the working member; the cam being rotatable to engage the top face of a positioned die and move it downward against the force of the spring arm 58 to operating position and to retain it in such position. The cam may be operated by an arm 62 fast on the spindle 61, and projecting toward the front of the machine.

The carriage T has an arm 63 at the rear extending upward and then forward somewhat U-shaped and provided with a head 64 located immediatelyabove the middle portion of the body 37 of the die carrying member, and overhanging the cam and lever dcvice for advancing the die in the holder. The head 64 has a plane lower face 65 lying parallel with the top oi' the carriage, and hence with a plate secured thereon. A pressing member is interposed between the head 64 and the underlying portion of the working member and is shown as comprising a block 66 having a channeled upper portion, in which are located antifriction devices such as rollers 67 that reduce friction between the block and the head 64. The part 37 of the working member is provided with a cylindrical segment portion 68 that has a rolling engagement with the lower plane face of the block 66 as shown in Figs. 3 and 6. The curved face of the portion 68 is concentric with the disks 40 of' the working member that have a rolling movement over the table. By means of this engagement, when the working member is rocked by grasping the handle portion 38, the pressing member will have a rectilinear movement in engagement with the head 64, and will also have a rolling engagement with the cylindrical segment 68 of the pressing member. During this movement the lever 62 operating the cam 60 will serve to bring the selected die into engagement with the plate l? with the proper amount of pressure to impress the character of the die in the plate. A

For 'the purpose of shifting the plate P fast on the carriage a known distance to accommodate for different widths of characters on the dies, an indicating disk 70 is secured at one end of the table, concentric with IOO IOS

and surrounding the screw rod 27. Instead of the arm 28 being `tast on the screw rod, the arm may be rotatable thereon, and carry a spring pawl 7]. that engages the teeth of a ratchet wheel 72, the latter being secured on the screw 27. Upon. rotation of the arm in one direction the pawl will engage the wheel 72 and turn the screw, but the screw will remain stationary when the arm moves in the reverse direction. -The arm may normally rest against a stop pin 7 4t on the disk 70, the ratchet teeth 75 are spaced equidistant, and upon moving the arm backward a distance of one, two or a certain number of teeth, and then advancing the arm, the ratchet wheel will rotate the screw a certain known distance. On the disk 70 are indicating marks at 76, 77 and 7 S; and a pointer 7 9 on the arm 2S registers with these indications. Certain characters may require a spacing of one unit distance or the distance ot one tooth in which instance the pointer that normallltT indicates at 76 with the arm engaging the pin 74, is brought to register with the indications at 77. Certain other characters may require the spacing of two ratchet teeth in which case the pointer may be moved to the indication at 78 and then the arm retracted, which will advance the screw for two ratchet teeth. Other characters may require three spaces and the arm is advanced to the indications at 80 and retracted, when the screw will be advanced three ratchet teeth.

It desired. suitable means maj)T be provided. for preventing slip in the rolling engagement between the pressing member and the die carrier or working member. In Fig. 6 a lug S1. is shown depending from the block 66 of the pressing member on each side. And a pin S2 on each side of the segment 68 engages the walls of a slot 83 in the lug 8l.

A modification oi the slip preventing means is shown in Fig. 7 comprising a gear tooth 84 on the pressing member that is en.- gaged. by pins 85 and S6 on the segment 68. The gear tooth having epicycloidal faces will produce a true cycloidal movement between the segment 68 and the pressing member.
